摘要

在一个准光学行波谐振器中，通过 532 nm 皮秒激光激活砷化镓开关，实验证明了对 20 kW、170 GHz 陀螺仪输出辐射的压缩。当皮秒激光脉冲能量达到 50 mJ 时，压缩比为 20。压缩脉冲的功率估计为 0.4 兆瓦。压缩脉冲的持续时间不超过 1.2 毫微秒，小于谐振器的往返时间。

Compression of 20 kW 170 GHz Gyrotron Output Radiation by Quasi-Optical Resonator With Laser Activated GaAs Switch

A compression of the output radiation of a 20 kW, 170 GHz gyrotron has been experimentally demonstrated in a quasi-optical travelling wave resonator with a gallium arsenide switch activated by a 532 nm picoseconds laser. A compression ratio of 20 has been obtained when the energy of picosecond laser pulses reached 50 mJ. The power of compressed pulses has been estimated at the level of 0.4 MW. The duration of compressed pulses did not exceed 1.2 ns which was less than the resonator round-trip time.
